    V5-TF is the ultimate air-free tacky flux engineered for mission-critical electronics (EV, UAS, eVTOL). Utilizing our proprietary AIRfree™ Core Technology, V5-TF guarantees six-sigma consistency and uninterrupted flow for high-precision dispensing, delivering superior NC REL0 True No-Clean reliability for demanding environments.

    Product Description

    V5-TF: Next-Generation Air-Free Flux for Critical Industrial Applications

    Overview: Six-Sigma Consistency for Demanding Electronics

    V5-TF is the ultra-high reliability, premium edition of our V5 resin chemistry, specifically engineered for critical industrial applications like aerospace (eVTOL, HALE, UAS) and electric vehicle (EV) manufacturing. It utilizes our proprietary AIRfree™ Core Technology, a consolidated manufacturing process that removes microscopic air bubbles common in conventional fluxes. This unique approach ensures six-sigma consistency and uninterrupted flow, which is vital for high-precision metered automated conveyor dispensing and achieving superior solder joint integrity in demanding environments.

    Key Features & Benefits (The AIRfree™ Advantage)

    Feature V5-TF Advantage Significance for Critical Assemblies
    AIRfree™ Core Technology Provides a highly homogenous paste with virtually no microscopic air bubbles. Dispensing Reliability: Guarantees uninterrupted flow, eliminating splatter and inconsistent dispensing issues on high-speed lines.
    Six-Sigma Consistency The highest level of material quality assurance available in flux paste. Yield & Quality: Ensures extremely low voiding rates and repeatable performance, necessary for mission-critical systems.
    QC-Aid™ Tracers Includes Optical UV-Tracer and Olfactory Tracer. Inspection: Allows for instant, non-destructive visual and sensory quality detection.
    Premium V5 Chemistry Superior NC REL0 True No-Clean resin-based formulation. High Reliability: Residues are inert and non-conductive, simplifying processes in complex, high-density PCBs.
    Thermal Stability Maintains robust activity across a wide range, supporting high-temperature lead-free and hot air rework (up to 450°C). Robustness: Ensures strong, reliable solder joints resistant to vibration and mechanical shock.

    Application-Specific Design Considerations

    • Aerospace & Defense (EVTOL, UAS): Required for applications where even minimal voiding or dispensing inconsistencies can compromise system integrity due to extreme temperatures, altitude, or vibration.
    • High-Precision Automation: Mandated for advanced assembly lines using high-precision dispensing equipment that cannot tolerate air pockets or rheological variance.
    • Universal Utility: Equally suitable for BGA/reballing and hand soldering where the absolute highest quality and consistency are non-negotiable.

    Compliance and Standards

    • NC REL0 Rated: Achieves the highest reliability standard for no-clean fluxes. Zero resistance without heat activation.
    • Halogen-Free Compliance: Meets the strictest industry requirements.
    • REACH-compliant: Made using REACH-compliant, premium raw materials.

    Suitability

    Rework, BGA, automated machines or hand soldering

    Designation

    • REL0 classification - Resin-based, low activity. Not corrosive. Halide-free (<0.05%). Surface insulation resistant. No copper mirror breakthrough. Low electrochemical migration (<1 decade drop)

    Viscosity

    30-50 mPa/s (Malcom @ 10 RPM/25ºC (x 10³mPa/s))

    Cleaning "No-Clean"

    “No-clean” indicates cleaning method as defined by IPC standard and does not mean that the flux leaves no residue. No-clean rather means that the flux can be left on PCB for several consecutive SMT assemblies but also won’t cause corrosion if left indefinitely. However, cleaning can be necessary and it is desirable. No-clean fluxes are easily removed using industrial solvents in ultrasonic devices or using commercially available flux residue removers like STIRRI HydraSweep™.

    Dispensing Kit

    This product does not include any Dispensing Kit - a separate purchase! 

    Dispensing Kit is an add-on for manual dispensing, used to create a pressure with a plunger similarly to a medical syringe.

    Air syringes intended for pneumatic dispensing machines use a piston stopper instead of a plunger. Do not remove the piston as it delivers the best seal preventing contact with air!

    Compliance

    This material is certified REACH-compliant - does not use any raw materials from the REACH restricted list of substances of high concern.
